GUN-SIGHT.

SPECIFICATION forming part of Letters Patent No. 410,422, datedSeptember 3, 1889. I Application filed Pebruaryl, 1889. Serial110,300,034- (No model.)

To aZZ whom it may concern.-

Be it known that LBENJAMIN LONG, a citizen of the United States, and aresident of Boulder, in the county of Boulder and State of Colorado,have invented certain new and useful Improvements in Gun-Sights; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to gun-sights.

The object is to produce a combined gunsight and distanceindicator whichshall be of such construction that the person using it may withreadiness and certainty determine the distance of an object from thepoint at which he stands, and also the angle at which to elevate thebarrel of the gun; furthermore, to produce a gun-sight which maybesecured to any gun or rifle at but a slight expense, and which will beconducive to more perfect long-distance shooting than the ordinarysights now in use, and, final1y,-to produce a gun-sight which,'whilebeing comparatively simple of construction, will be found of the highestefficiency and utility in use.

WVith these objects in view, the invention resides in a gun-sightconsisting, essentially, of a sight-carrier hinged in a suitable mannerto the barrel of the gun, the said sight-carrier being provided with alever, by means of which it may be elevated to any desired distance;furthermore, in the combination, with the said sight-carrier, of amovable sightpieoe and means for op erating the sam e,whereby when thesight-carrier is raised the sightpiece will also be raised, so as toenable the marksman to determine any distance that may be desired;furthermore, in the combination, with the sight-carrier having a leversecured thereto to elevate the same, a'sightpiece moving within thesight-carrier and designed to enable the marksman to determine thedistance of an object, of a spring for operating both the sight-carrierand the sightpiece to cause the former to resume its normal positionafter being used and the latter to be raised when the sight-piece israised; and, finally, the invention consists in the various noveldetails of construction whereby its objects are attained.

mounted thereon.

In the accompanying drawings, forming part of this specification, and inwhich like letters of reference indicate corresponding parts, I haveillustrated one form of device embodying the essential features of myinvention, although the same may be carried into effect in other wayswithout in the least departing from the spirit thereof.

In these drawings, Figure 1 is a side view of a portion of a gun-barrelwith the sight Fig. 2 is a top plan view of the same. Fig. 3 is an endview. Fig. 4 is a longitudinal sectional view. Fig. 5 is a bottom planview of the sight-carrier. Fig. 6 is a detail view of a tilting slidecarrying the sight, and Fig. 7 is a detail view of the spring foractuating both the tilting slide and sightcarrier.

Referring to the drawings, A designates a gun or rifle barrel upon whichis mounted my improved sight. This sight may be secured on the barrel atany point convenient to the eye.

B designates the sight-carrier,on one side of which is formed a lever 1,which fits down against the side of the gun-barrel, and is provided onits outer end with a button 2, by means of which it may be moved. Theforward end is provided with an opening designed to be engaged by ascrew 3, which passes through two ears 4, formed on a crosspiece 5,which is dovetailed on its lower side and fits in a dovetailed recess 6,formed in the barrel. The rear end of the sight-carrier fits in asimilar cross-piece 7, secured in the same manner to the gun-barrel, sothat the said carrier is always held in its proper position, and isprevented from being knocked out of adjustment by side blows or by thepiece falling.

' At the rear end of the sight-carrier, or that portion next the breechof the gun, is formed an opening 8, and the under portion of thesight-carrier is cut out to form a recess 9, in which fits a tiltingslide 10. This slide is held in position in the sight-carrier by meansof a screw 3, and extends up level with the top of the sight-carrier andcarries on its outer end a lip 12, provided with a sight-notch 13.Immediately in front of the sight-notch the metal is cut away to form agroove 14, so that the sight on the muzzle of the barrel will not beobstructed from view. 3

Upon the screw 3 is mounted a spring 15, the ends of which are formedinto coils 16, the ends 17 of which extend out, as shown. The upper end18 is designed to rest upon the top of the tilting slide 10, and theends 17 to extend through the recess 19 in the sightcarrier and restupon the cross-piece 5. Thus .when the lever is pressed down the springwill cause the tilting slide to be forced out and thus tilt up the endcarrying the sightnotch; but as soon as the lever is released the ends17 of the spring will force the sight-carrier down to its normalposition. The ends of these wires serve to limit the height to which therear end of the sight-carrier may be moved, for when it has reached itshighest limit the wires come in contact with the upper edge of therecess 19, and thus prevent its being raised any higher, and by reasonof the curved shape of the lower end of the sight-piece the rear end ofthe sight-carrier will be raised more rapidly at first, and less rapidlyas the said end is raised higher.

On each side of the rear end of the sightcarrier is mounted a slide 20,provided with a slot 21, through which extends a screw 22. In each ofthese slides are formed a number of small openings 23, carryinghorizontal wires 24, the ends of which are coiled around the screws 22,as shown. These wires are designed to be used to determine the distanceof an object from a certain point, as will be described farther on.

Upon the gun-barrel may be marked a graduated scale 25, each linerepresenting one hundred yards, and on the lever 1 is formed anindicator 26, which enables the marksman to determine the elevation ofthe piece. Thus when the indicator coincides with the marks on the scalethe rear end of the sight-carrier is elevated to the proper height forshooting at the distance indicated by the figure to which the indicatorpoints.

In using this device the perpendicular distance between the bottom ofthe notch 13 and the first horizontal wire above it will measure aperpendicular height of one foot at a distance of one hundred yards. Byfastening the device nearer to the eye, or by raising the adjustablewires and increasing the space between them, a perpendicular height oftwo or three feet or more may be measured by the perpendiculardistancebetween the notch and the wire. This sight may be so adjustedthat the first space will measure one or more feet at one hundred yards,two or more feet at two hundred yards, and so 011. Thus when the rearend of the sight-carrier is raised to such a height that the firsthorizontal wire disappears, then the marksman knows that the objectaimed at is two hundred yards or more distant, or when raised to thesecond wire the object is three hundred yards or more, and when raisedto the under side of the inward-projecting lugs 27 on the top of thesight-carrier, which serves as a third horizontal wire, he then knowsthat the object is fourhundred yards or more distant. In practicalshooting, the marksman, 011 looking at the object through. thesight-carrier, can tell at a glance which one of the spaces between thewires most nearly covers the top and bottom of the object to be aimedatsay the feet and head of a man or the feet and back of a deer. Themarksman then raises the rear end of the sight-carrier until thenotchsight comes to that space, when by consulting the graduated scalehe may readily determine the distance of the animal.

It will thus be seen that although this sight is comparatively simple ofconstruction it will admit of more accurate shooting than sightsheretofore constructed, for the reason that it acts not only as a sightbut as a measuring device.

Having thus fully described my invention, what I claim as 116\ anddesire to secure by Letters Patent, is-

1. In a un-sight, the combination of the sight-carrier, a sight-piecepivoted therein and provided with a forwardly-curved reduced portion,and a spring exerting a downward pressure on the sight-piece, and havingthe rear portion thereof seated in the angle formed between the forwardreduced portion and the rear enlarged portion of the sight-piece,wherebywhen the sight-carrier is raised the sightpiece will be forced out andraised simultaneousl y therewith, substantially as described.

2. In a gun-sight of the described class, the combination, with thehinged sight -carrier provided with a rear opening and having a suitableoperating-lever, of the movable or tilting slide disposed beneath thesight-rearrier in the recess thereof and having a sightnotch on itsouter end, and the vertically-ad justable horizontal wires passingtransversely through the opening in the sight-carrier, sub stantially asset forth.

3. The combination of a gun-barrel having a graduated scale on the sidethereof, a sightcariier lever pivoted on the said barrel, a sight-piecepivoted within the carrier and provided with a forwardly-curved reducedportion, a spring for exerting a downward pressure on the sight-piece,and having the rear portion thereof seated in the angle formed betweenthe forward reduced and rear enlarged portions of the sight-piece,whereby when the carrier is raised the sight-piece will be forced outand raised simultaneously therewith, and a lever on the carrier havingan indicator moving over the said scale, substantially as described.
